'Rigged' Wall Street does investors out of billions, claims best-selling author Lewis

The US stock market is rigged in a way that benefits sophisticated traders at the expense of other investors, according to best-selling author Michael Lewis.

High-frequency traders can, in an instant, purchase shares and re-sell them to investors at inflated prices, claims Lewis who is promoting his new book ‘Flash Boys: A Wall Street Revolt’.

The firms involved use this capability to do investors out of billions of dollars.
